ALL invite codes for the demoplatform have expired!

All of the invite codes state they expired on 31-12-2021. So it looks like you need to update all of the pages, or your code generator with new codes that expire later this new year.

An example course: Gitlab Certified Project Management Course
Try to make a new temporary account here with an invite code given on the course page: GitLab Demo
You are told that the code expired.

So I cannot do any of the actual exams for the certification. Other people are having this problem too on the edcast pages. Please fix it asap.
